IMPROVEM ENT IN PLOW-BEANIS.

Specification forming part of Letters Patent No. 111,764, dated February14, 1871.

1'0 all whoml it may concern,.-

Be it known that I, SAMUEL HOLDEN MILL- ER, of Hamilton, Hancock county,Illinois, have made a new and useful Improvement in Plow-Beams, &c., ofwhich the following is a specification.

The object of my invention is to prepare the ordinary style of plows toavoid the disadvantage of weeds clogging under the beam,to make the beamto be variously adjustable, and to improve several details. To do this Imake and arrange the beam parts and other portions of the ordinary styleof plows substantially as set forth and shown herein and in theaccompanying drawing, having letters of reference to the several partscorresponding with those herein used for reference, and in which- Figurel is a side elevation, showing the peculiar parts of my invention inploWs.

A represents the standard of any ordinary pow, and B represents the backparts of the ordinary beam, to which the usual parts-as share,mold-board, and handles-belong, but are not shown in the drawing. Thestandard extends some distance above the beam B, as A, and bears a topbeam, O, which plays on it, as on a pivot, horizontally. The beam Breaches only to the standard A, to which it is fixed. The top beam, C,runs forward, as usual in plow-beams, and backward some distance overthe beam part B. Under the back end of C is xed a step part, D, and thisrests in either one of a number of depressions, H H H, at differentheights in a movable grade block, E, which rests on beam B. A bolt, F,passes through beams B and O and parts D and E, to hold the whole in Xedbut adjustable relations, so that the height of the fore beam, O, towhich the team is attached, may be varied to suit different depths ofplowing. Ihe handles and plow are attached to beam B in the usual way.The beam B is broad at the bolt F, and has a slot through which thatbolt passes, which admits that bolt being set toward either side to varythe lateral adjustment of beam O to suit a different number of horsesused abreast. This may be done, also, by having a slotted plate on topof beam B for the bolt,instead of passing through B. The beam C reachesforward to the team as an ordinary beam, lout at such a height elevatedabove the usual position as not to be liable to clog by weeds, vegetablematter, 6to. Under beam O is a draft-rod, I, which has eye-jointconnections to the beam C at its back end and to bolt K at its frontend. The bolt K has an eye-j oint connection to the beam C, and passesdownward through the double tree L and draft-rod I, and has a nut underall on its lower end. The whole is so arranged that the doubletree Lwill be suspended at its usual height and not drop when the horses slackup or go to make a turning, and act to a disadvantage With the horses7legs, as in the ordinary way. The double-tree L can be made to suit one,two, three, or four horses abreast, which number may be varied bylateral adjustment of beam G, as referred to above.

This improvement may be adapted to old or new plows and admits ofmodification.

I claiml. The combination and arrangement of plow-beams B and C, theparts D and E, F and Gr, all constructed and operating as set forth.

2. The combination and arrangement of the front end of beam O, draft-rodI, bolt K, and doubletree L, all constructed and operating as set forth.
